I had sex for the first time on April 10th. We used a condom correctly, and it didn't break, though he did finish inside the condom. I bled after, and this continued as spotting the next day. Was this implantation bleeding? My period was due the 26th, and I am already a day late, with no symptoms whatsoever aside from slight cramping, discharge, and backache. I may be stressing myself out, as I cannot handle a child at this point in my life and condoms are the only BC available to me at this time. Thank you in advance.
